Patent DE-3533731-A1 (DE)
Title: Sealing arrangement for a piston/cylinder unit
Inventor: VOLZ PETER DR
IPC: F16J15/3236
Filed: 1985-09-21
Abstract: The invention starts from a piston/cylinder unit, in particular for hydraulic actuating devices in motor vehicles, which has a piston 4 guided in a cylinder housing 2 in a cylinder bore 3. The piston 4 has an annular groove 5 in which a primary sealing-ring collar 6 of U-shaped cross-section is arranged. The primary sealing-ring collar 6 has a radially inner sealing lip 17 bearing on the annular groove 5 and a radially outer sealing lip 18 sliding in the cylinder bore 3. The main cylinder 1 has a follow-up connection 16, 12, 10 and 23 which, in the case of a pressure gradient from a follow-up space 12 to a pressure space 29, allows pressure fluid to subsequently flow past the radially outer sealing lip 18 into the pressure space 29, in the course of which the outer sealing lip 18 moves radially inwards due to the pressure fluid. A pressure-space-side side face 8 of the annular groove 5 is formed by a spring plate 31 supported on the piston 4. To simplify and reduce the cost of the piston/cylinder unit, it is proposed that the primary sealing-ring collar 6 be arranged on the piston 4 with inner axial, elastic preloading. <IMAGE>

Patent DE-3632179-A1 (DE)
Title: Circuit for monitoring signal lamps
Inventor: HURTIG GUENTHER
IPC: H05B37/03
Filed: 1986-09-22
Abstract: A voltage (UJ*) which is derived from the lamp current is compared with a voltage (UL*) derived from the supply voltage (UL), in a lamp monitor. The difference voltage (UD) which is formed from the two voltages is used, via a threshold value switch, for emitting defect messages. In a network (N) of non-linear resistors (R1, R2, R3, Z), voltage (UL*) which is derived from the supply voltage is set to values which correspond to the voltage behaviour of the voltage (UJ*), which is derived from the lamp current, in the event of a lamp current at a normal level. The circuit can be used over a relatively large voltage range of the supply voltage (UL) without sensitivity being adversely affected. <IMAGE>

Filed: 1987-01-23
Abstract: The invention describes a composite material comprising a matrix of plastic and at least one reinforcing inlay of plastic, where the matrix permeates the reinforcing inlay and is in the stressed (tensioned) state within the finished composite material. The invention likewise relates to a process for the production of the composite material, in which a reinforcing inlay of a pre-stretched plastic having internal strain is laid into a matrix precursor in such a way that the matrix precursor permeates the reinforcing inlay, the matrix precursor is cured to form the matrix, and simultaneously, during the curing of the matrix precursor, the reinforcing inlay is subjected to an elevated temperature which is sufficient to cause at least partial recovery and thus stressing of the pre-stretched plastic. The novel composite material is suitable for the production of mouldings having excellent mechanical properties, in particular high elastic rigidity.
Patent DE-3703238-A1 (DE)
Title: Adjusting device for an ejector on presses
Inventor: JUNKLEWITZ HUGO DIPL ING
IPC: B21D45/02
Filed: 1987-02-04
Abstract: The application discloses an adjusting device for an ejector (5) on presses. The ejector operates with a drive control cam (46) which imparts an oscillating motion to a rocker lever (30). This oscillating motion is transmitted to an ejector lever (26) which imparts a predetermined reciprocating motion to the ejector (5). The forwardmost position of the ejector (5) is to be constant. The changes in the stroke are achieved by changing the rear end position. The change in stroke is effected by swivelling a curved piece (36) relative to the ejector lever (26), on which it is pivoted. The swivelling motion is effected by way of a self-locking mechanism (31) on the ejector lever (26). The mechanism (31) is kinematically connected to a fixed actuating drive (8) only in the forwardmost position (A) of the ejector (5). The rigid, positive connection makes possible a precise and automatable adjustment of the die-side ejector stroke. The actuating drive (8) and the measuring device (19) are mounted directly on the machine frame. <IMAGE>

Title: Process for the operation of a bioreactor operating anaerobically
Inventor: FUCHS FRANZ
IPC: C12M1/107
Filed: 1987-03-25
Abstract: Bioreactors of this type are used for anaerobic degradation of organic substances. On continuous operation of these bioreactors there is the risk of blockage owing to the growing together of large amounts of bacteria which leads to blockage of the system and thus interruption of continuous functioning. According to the invention, the bioactive bacteria colonise the surface pores of carrier bodies which are continuously circulated in parallel with the stream of water to be treated and thus are simultaneously continuously dispersed and rearranged and thus, thirdly, as a consequence of friction with one another and with the tank and pipe walls undergo abrasion and thus regeneration on their surfaces. The process according to the invention is particularly suitable for degradation of organic constituents produced continuously, and great variations both in the amount and in the intensity of pollution with organic substances are permissible. <IMAGE>

Patent DE-3711626-A1 (DE)
Title: Method and apparatus for producing a carrier body for a catalytic reactor
Inventor: KUCHELMEISTER REINHOLD ING GRA
IPC: C23C4/08
Filed: 1987-04-07
Abstract: Known production methods for carrier bodies of catalytic reactors in which wound metal strips are firmly connected to one another by brazing material in powder form or in the form of liquid brazing paste make it necessary to provide a binder which is put onto the surface of the metal strips before the powdery application of brazing material or is contained in the liquid brazing paste. During the heat treatment of the carrier body for the actual brazing operation, this measure leads to undesirable contamination of the furnace. It is therefore proposed that the brazing application be carried out by thermal spraying, in particular by plasma spraying, on both sides of a metal strip. This development enables the brazing material to be thrown by means of a flame and in the form of particles at high speed onto the strip surface. The surface of the strip itself is neither melted nor fused because of this. The mechanical properties of the strip therefore do not change. A very thin brazing application is also possible. An apparatus suitable for the novel method is described. The novel method and the apparatus are suitable for applying brazing filler metal to metal strips which are wound into a matrix form.

Title: Device equipped with multiple pistons and with flywheels and intended for the maintenance of a constant torque
Inventor: KERL WERNER
IPC: B62K23/00
Filed: 1987-05-30
Abstract: Most known drive applications require a virtually constant output torque over the entire range of adjustment. For this purpose, complex specially designed, if required regulated, adjustable drives are required. The new device is intended to convert the inconstant input torques in such a way as to give rise to constant torques on the output shaft. When the abovementioned device is used, an inconstant output torque is converted into a constant output torque by the eccentrically acting 180@-offset masses of at least two freely movable rotating flywheels with 2 x 2 guide pistons which are installed in a common housing with the input shafts and guide cylinders. The torque can be adjusted at any time while this unit is running by means of pull mechanisms or equivalent systems. When its many possibilities for combination and use are exploited, the device can be produced simply and inexpensively to virtually a single design for all applications where at present expensive and complex constant-torque regulators and adjustable drives are in use. <IMAGE>
